GOLF PUTTER AND METHOD OF FORMING THE SAME.

Application filed September 22, 1926. Serial No. 137,043.

This invention relates to improvements in golf clubs and particularly to golf club heads and to the method of making the same. The invention concerns primarily a golf putter although itmay be applied to several other golf clubs commonly referred to as the irons, such as the midiron, mashie and similar clubs.

An object of this invention is to provide a golf club head such as a head for a putter,

ence is had to the accompanying drawings for-an illustrative embodiment of the invention, wherein:

Figure 1 is a perspective view of a putter head embodying the invention, v

Fig. 2 isa vertical section taken substantially on the line 2-2 of Fig. 1, and

Fig. 3 is a vertical section taken substantially on the line 3-3 of Fig. 2.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the general exterior shape of the club may be varied un der various circumstances, but in all cases it has the general shape of the conventional golf club head. The improved head consists of an outside shell 10 preferably formed of a relatively hard metal. This metal in the preferred form of construction is aluminum or an aluminumalloy, although it may be changed using brass, bronze, copper, mild steel orany equivalent substance. Inside of the shell there is cored out a longitudinal cavity 11-, one end of which is open at the outer or free end of the head. In forming this cavity in the shell, a plurality of small rojections 12 are referably formed on the interior of the she I. The cavity 11 is then filled with a relatively heavy metal 13 which in the preferred form of construction is white metal, although this may be lead or 55 any alloy of lead or any equivalent metal which will give the desired weight. This heavy metalfully occupies the cavity 11 and extends from the open end or the free end of the head to the base of the neck 14 which receives the shaft.

In constructing the improved head, the

shell is first cast, a core being employed to form the cavity 11 and the opening through the neck 14. This core is so formed that when the shell is cast, the projections 12 will be formed thereon. After the shell is cast, it is heated to a temperature very nearly as high as the melting point of the metal forming the shell. 'While under this temperature the heavy metal 13 is poured into the cavity and the complete club head allowed to cool. 1n constructing the club head it is quite important that the club head he made in the above mentioned manner for the reason that the shrinkage of both metals during cooling will be approximately the same and the heavy metal 13 will be tightly held within the shell 10. If the heavy metal 13 is poured into the shell while the shell is cool, on cooling the heavy metal will tend to shrink and pull awa from the interior surface of the shell, so t at the heavy metal will be loose within the shell. When the heavy metal and the shell are both heated and cooled together, the heavy metal will remain tightwithin the shell. The projections 12 serve to keep the heavy metal from falling out of the cavity. When so much of the head is com leted, the opening in the neck 14 is reame out and the shaft is inserted into it.

It will be found that a club constructed in the above described manner has a very nice balance and has the desired amount of weight in the head without making a large sized head. The relatively hard outer shell serves as a good rotective medium which cannot be easily eformed or bent out of shape. If the soft metal were exposed, on the surface of the club on placing the club in a bag with other clubs, the other clubs would be very apt to scar the soft metal and deform it. In this way the relatively hard outer shell protects the soft metal. It will also be found that in using the improved,

club on striking the ball there is a pleasing click as distinguished from the dull thud which occurs in using clubs of prior constructions.

From the above described construction it will be appreciated that a novel golf club is provided having a relatively hard outer shell enclosing a relatively soft heavy metal, thus giving the desired weight to the head without causing the head to be of an I unusually large size.

It will be understood that various changes may be made in the detail of construction without departing from the spirit and scope of the invention as defined by the appended claims.

I claim:

1. The method of making a golf club head which consists in casting a shell having a neck portion extending therefrom, allowing the same to cool, heating the same to a temperature just below the melting point of the metal forming the shell, pouring heavy metal intothe shell through the neck to said body portion, and allowing the shell and heavy metal to cool.

2. A golf club head 00m wiring a substantially angular tubular shaped member which has .a cavity extending therethrough one end of said tubular shaped member providing a reduced neck portion, and the other DAVID H. FINDLAY.
